ABSTRAKT

Numerical studies employing the mixture model were used to evaluate, through sensitivity analysis, the influence of closure coefficients and turbulence scales on a fully developed homogeneous solid-liquid suspension flow. A standard k-ε turbulence model was employed with a 20% increase for each closure coefficient; its effect was evaluated and compared with results in the literature. For turbulence length scales, several methods described in the literature served as references. The numerical results of the mixture model simulations, for a fully developed homogenous flow of solid-liquid suspensions in a circular pipe section, were compared with those in the literature. Overall, the obtained results and the literature results matched, validating the model for use with fully developed flow of neutrally buoyant particle suspensions.
